To ctZZ whom it may concern: 7

Be it known that I, ALDIN Bunsen, a citizen of the United States,residing at Westford, in the county of Otsego and State of New York,have invented certain new and useful Improvements in Closures for Jars,&c.; and- I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements in closures for jars, &o., and hasparticular relation to the construction of mechanism for retaining thejar-top in position to close and seal the jar.

One object of my invention is to provide a construction which is neatand attractive in appearance, durable in construction, simple andefficient in operation, and which can be made at a moderate cost.

A further object is to provide a closure which can be readily attachedto and detached from the jar and which when placed in proper positionwill be lockedagainst movement.

A further object is to provide a constructwo sections is employed, thesections being hingedly connected, said band being adapted to be lockedat the opposite ends of said sections', a connectingportion beingformed, said portion leading from the hinged connection to the oppositesides, the locking ends of said sections being held in locked positionby said connecting bar or portion.

A further object is to provide a construction in which an encirclingband is employed,

said band being formed in two sections hingedly connected, the free endsof said sec tions, being adapted to be locked together, a connecting baror portion being formed extending from the hinged portion of the sections to the opposite side of the jar, the free or looking ends of saidsections being embraced by said connecting portion or bar.

A further object is to provide a construction in which an encirclingband is employed, said band beingformed in sections hingedly connectedand adapted to be locked at their free ends, said sections being placedin posi tion or taken therefrom by a movement of said sections on theirhinges and in the same horizontal plane.

To these and other ends, the nature of which will be readily understoodasthe invention is hereinafter described, s'aidinvention consists in theimproved construction and combination of parts hereinafter fullydescribed, illustrated in the accompanying drawings, forming a part ofthis specification, and particularly pointed out in the appended claims.

In the drawings, in which similar numerals of reference indicate'similarparts in all of the views, Figure 1 is a side elevation of a P0P,

tion of a jar, showing my improved closure thereon. Fig, 2 is a centralvertical section of the structureshown iii-Fig. 1. Fig. 3 is aperspective view showing the parts composing my preferred form ofclosure, the parts being shown separated. Fig. 4 is a similar viewshowing a modified form.

Various methods have heretofore been employed in sealing jars, thepurpose being to clamp or secure the jar-top in a sealed contact withthe jar. One of these methods consisted in placing the top in position,forming a substantial air-tight seal, the clamping or the screwing ofthe closure in position which followed serving merely to'firmly securethe top in its sealed position. In this class of closures the cooling ofthe contents formed a partial vacuum under the top, making it difficultwhen the closure was released to remove the top. Another form of closureprovided the jar-top with a vent or opening,

jar-top could be readily removed. To this class of closures the presentinvention is intended to apply.

The invention disclosed herein presents a construction in which anencircling band, formed in two sections hingedly connected and adaptedto be locked together at its free ends, is employed to form the supportfor a connecting portion or bar which extends over the top of the jar,the latter carryinga screw which is adapted to close the vent in thejartop, the act of closing said vent serving to lock the free ends ofthe encircling band in a locked position. The encircling band having ahinge connection retains a relative horizontal alinement between itssections whether the sections be open or closed. Two forms of closuresembodying this construction are shown. In one form the parts are formedin separate pieces, including the connecting portion, but which whenready for use presents the appearance of but two memhere, this formbeing preferred by reason of its being manufactured to a greateradvantage than the other form shown, the latter having the connectingbarand one of the sections forming the encircling band for-med integral.Another difference consists in the manner in which the free ends arearranged when in locked position.

In the use of the closures herein described and, in fact, in allstructures making use of the vent it is essential that a shoulder orshoulders be formed in:the jar-body, which shoulders form the supportwhich retains the support for the vent-closing device against verticalmovement under the pressure exerted in sealing the jar. These shouldershave been provided in various forms; but in the present invention it isfound preferable to employ a peripheral groove of sufficient depth toreceive the encircling band, so that a flush surface will be formed onthe outer face of the jar. It is to be understood, however, that thedevice may be used in con- 7 nection with a jar having simply an annularor peripheral shoulder or with a series of projecting portions extendingradially from the surface of the jar, said portions having theircontacting surfaces arranged in horizontal alinement.

A prominent feature of the invention herein disclosed consists in thefact that the closing movement of the sections is limited, it beingimpossible to move the sections inwardly beyond a position where acomplete circle is formed. This forms a protection against theaccidental breaking of the jar, the encirclingmetallic band preventingthe jar from receiving the strain if a blow isaccident-ally struck alongthe surface of the jar contiguous to the band, the stops formed at theend of the sections preventing the band from moving or being driveninwardly against the surface against which it contacts.

To enable a better understanding of the Trention, I will now describethe parts in 1 press against the rubber closure 5. tion 14 may be formedwith a flat face or may detail, the construction being illustrated inthe drawings.

1 designates the jar-body, of any suitable configuration, having nearits upper end a peripheral groove 2, adapted to receive the encirclingband.

3 designates the jar-top, which, as herein shown, has its under sideconcave to form a vacuum-chamber. The top 3 is adapted to be placed on aring of suitable material, laid on the upper edge, a portion of the topextending downward inside of the jar to a point below the upper edge ofthe jar-body, as shown in Fig. 2. The jar-top is provided with a centralopening or vent 4, the upper face of the jar-top having a suitable faceto receive the rubber closure 5, which may be either placed looselythereon or may be car ried by the clamping-screw, as hereinafterdescribed.

6 designates the encircling band, composed of sections 7, eachsubstantially of half a circle, said sections being pivotally orhingedly connected, as at 8. In the form shown in Figs. 1, 2, and 3 thepintle for the hinge portions of the sections is formed on one end ofthe connecting portion orbar 9, thelower end of said pintle beingriveted after said sections are placed thereon. The free ends of thesections are provided with outwardly-extending portions 10 of a lengthequal to the thickness of the portion 9, said portions being separatelyof a height less than the height of the section, the two portions 10when combined equaling the height of said sections. The two portions 10are of unequal height, the greater being arranged at the upper portionof its section, and the smaller being arranged at the lower portion ofthe opposite section. The connecting bar or portion 9 has its free endprovided with a vertically-extending elon gated slot 11 of a lengthgreater than the height of the sections, said slot being adapted toreceive the portions 10. In assembling this structure the knuckleportions of the sections are placed on the pintle and the latterriveted. The section having the portion 10 of greatest height is thenmoved to a position wherethe portion 10 maybe sprung into the slot 11.As the opening 12 in the bar or portion 9, through which the otherportion 10 is to be passed, is of aless width than the height of thelarger portion 10, it will be readily seen that the larger portion 10must be sprunginto position and when in such position cannot pass out ofthe slot 11.

The normal position of said portion in said slot is at the upper endthereof, so as to allow the opposite portion 10 to readily pass withinthe slot 11 through the opening 12 when the closure is placed about thejar within the groove or recess 2.

The connecting bar or portion 9 carries a suitable screw 12*, having asuitable operating portion 13, the opposite end of the screw having aswiveled flat portion 14, adapted to The porbe formed with'an annularflange extending downward, the portion in the former construction simplybearing against the closure which is placed on the top 3 or may receiveand retain it, as shown in Fig. 2, where the depending flange is shownat 15.

The construction shown in Fig. 4 differs from that heretofore describedin that the bar 9 is formed integral with one of the sections andcarrying a knuckle to receive the knuckle formed on the oppositesection, the two sections being secured bya suitable pintle, a furtherdifference being in the form of the locking device. In this form theportions 10 are continuations of the section, the contacting faces ofthe two portions being inclined to form a look when the band is closedto form a continuous ring.

The operation will be readily understood. The jar is first filled withthe contents and the top placed thereon. The band 6 (which is open) isthen passed around the jar, within the groove 2, and closed until thefree end containing the portion 10 abuts against the end of the oppositesection, when the parts will be as shown in Fig. 1, or in case the formshown in Fig. 4 is used the portions 10 will overlap, in either caseforming a continuous encircling band. The screw 12 is then operated,closing the vent 4 and at the same time looking the portions 10 againstmovement in any direction. When the jar is to be unsealed, the screw 12is first operated to'release the closure 5, the same movement serving toallow the connecting-bar 9 to move, which movement allows the sections 7to be readily opened, whereupon the closure can be readily removed andthe jar opened.

By reason of the fact that the moving section 7 of the form shown inFig. 4 must be sprung (to a slight extent) into position this form is.preferably used in connection with a jar having only an annularshoulder and not a peripheral groove, said springing move ment obviouslypreventing the band from being secured Within an inclosed groove such asshown and within which the form shown in Figs. 1, 2, and 3 may be usedadvantageously. It will be seen, therefore, that I have provided aconstruction embodying two members hingedly connected, one of saidmembers carrying the connecting-bar, the two members being adapted whenclosed to form a completeencircling band the closing movement of whichis limited by the contacting faces of the meeting ends of said mem bers,said meeting ends overlapping and being in turn overlapped by saidconnectingbar.

By providing a construction in which the meeting ends overlap and are inturn overlapped by the connecting-bar I prevent all liability of themeeting ends being accidentally pressed outward after the closure is inposition, the overlapping of the connecting bar retaining and protectingthe meeting ends from such tendency. In addition to this, the fact thatsaid bar overlaps the meeting ends of the band causes said bar when thetop screw is being forced home to more firmly bind the parts together,the ends of the bar being drawn inward to a slight eX- tent in anobvious manner.

A number of other advantages appear from this construction; but it isnot thought necessary to point them out in detail, inasmuch as they willbe obvious.

While I have shown several ways in which the invention can beadvantageously made and used, I do not limit'myself to such pre ciseconstructions, but claim the right to use such other modifiedconstructions which will fall within the spirit and scope of my inven-'tion as set forth in the appended claims.

While I have shown and described the coin struction as applicable to aclosure for jars, it will be readily seen that the construction may beused as well as a means for carrying a heated jar, the weight of the jaras exerted by the shoulder formed on the periphery thereof serving tohold the two portions 10 in the lower portion of the slot 11, as shownin Fig. 1, in which position both will be locked within the slot, whilethe shoulder resting on the top of the construction shown in Fig. 4 willcause the portions 10 to be interlocked, so that as long as theconnecting-bar, which in this case would form the handle, is raised theband would be held in locked position, enabling the jar, whether hot orcold to be carried from one place to another.

Having thus described myinvention, what I claim as new is= 1. A closurefor jars, the, comprising two members, hingedly connected, one of saidmembers carrying the connecting-bar, the two members being adapted, whenclosed, to form a complete encircling band the closing movement of whichis limited by the contacting faces of the meeting ends of said members,said meeting ends overlapping and being in turn overlapped by saidconnectingbar; and means carried by said bar, for holding the jar-lid inposition. I

2. A closure for jars, the, comprising two members, hingedly connected,one of said members carrying a connecting-bar, said members when closed,forming a complete encircling band, the meeting ends of said bandhavingoverlapping projecting portions adapted to cooperate, saidprojecting portions being in turn overlapped by said bar, the closing ofsaid band being limited by the contacting faces of the meeting edges andtheir projecting portions; and means, carried by said bar, for holdingthe jar-lid in position.

3. The combination with a jar-body having a shoulder; of an encirclingband formed in sections, hingedly connected, one of said sectionscarrying a connecting-bar adapted to overlap and hold said sectionsagainst movement, the closing movement being limited,

whereby any tendency of the band to exert pressure against the side ofthe jar will be prevented.

4. Aclosure for jars, &c., comprising a plurality of members hingedlyConnected, the meeting ends of said members being provided Withradially-projecting portions, said members when closed, forming acomplete encircling band, the closing movement of which is limited bythe contacting faces of said meeting ends; a connecting-bar, carried byone of said members, said bar having a slot to receive said projectingportions; and means for retaining said projecting portions in. saidslot;

5. The combination with a jar-body having a shoulder; of an encirclingband formed in sections, hingedly connected, said band carrying aconnecting-bar provided with a slot and passage-Way to said slot, saidslotbeing adapted to receive the meeting ends of said band and retainsaid band in a closed position, the closing movement being limited.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
